Question

An object of mass 20 kg is pulled up with a force of 150 N on an inclined plane for a
distance of 3.0 m. The plane makes an angle of 30º with the horizontal and the
coefficient of kinetic friction between the object and the plane is 0.3. Draw the free body
diagram and calculate the work done by each force. (Take g = 10 ms −2

Answer 1

©Take any 2 directions as reference.

©See the forces that are actin Think in way of types of forces, gravitational, em(tension, contact.i.e., normal or friction nuclear or weak.

©Take its components along the reference axes and operate vector operations as force is a vector. Find things as desired.
